AMISULPRIDE ACTAVIS - Amisulpride - Dosage, Side Effects, Pregnancy

Treatment of schizophrenia.

Generally speaking

· If the daily dose is ≤ 400 mg, the administration will be in a
· Over 400 mg, the administration will be done in 2 doses per day.

Acute psychotic episodes

It is possible to start with the IM route for a few days at a maximum dose of 400 mg / day and then relay by the oral route.
The recommended oral dose is 400 to 800 mg / day, the maximum dosage should not exceed 1200 mg / day. The tolerance of doses above 1200 mg / day has not been widely evaluated. Therefore, these doses should not be used.

The dosage will then be maintained or adjusted according to the patient's individual response.
In all cases, the maintenance treatment will be established individually with the minimum effective dose.

Episodes: negative predominant

The recommended dosage is 50 to 300 mg / day. Dosages will be adjusted individually. The optimal dosage is around 100 mg per day.
Child and adolescent

The efficacy and tolerability of amisulpride of puberty at age 18 years have not been established: the available data on the use of amisulpride in schizophrenia in adolescents are limited Therefore, the use of amisulpride is not recommended from puberty until the age of 18 years. In children less than 15 years of age, amisulpride is contraindicated (see section Contraindications).
Person, aged

Friendulpride should be used with particular caution in this population because of the risk of hypotension and sedation (see Warnings and Precautions for Use).
< Br>

Renal insufficiency

Due to the renal elimination of amisulpride, the dose in patients with renal insufficiency should be reduced by half in patients with creatinine clearance (CICr) between 30 and 60 ml / min and To one-third in patients with creatinine clearance between 10 and 30 ml / min.
In the absence of data in patients with severe renal impairment (ICRC

Hepatic Insufficiency

Since amisulpride is weakly metabolized, dosage reduction is not necessary in patients with hepatic impairment

The tablet can be divided into two equal half-doses.

ANTIPSYCHOTIC, ATC code, N05AL05.

The amisulpride is an antipsychotic of the class of substituted benzamides.

Its pharmacodynamic profile is characterized by a selective and predominant affinity to the dopaminergic receptors, D 2 and D 3 of the limbic system, amisulpride has no affinity for receptors, serotonergic receptors and other neuroreceptors of Type, histaminic, cholinergic and adrenergic.

In large doses in studies carried out in animals, amisulpride blocks preferentially the dopaminergic neurons of the meso-limbic system compared with those of the striatal system. This specific affinity may explain the predominant antipsychotic effects of amisulpride compared to its extrapyramidal effects

Attention is drawn in particular to the risk of drowsiness associated with the use of this medicinal product in vehicle operators and users of machinery.
This medicinal product MUST NOT BE USED in the following cases

· Known hypersensitivity to amisulpride or to any other constituent of the product

Severe hypertensive accidents have been reported in pheochromocytoma carriers with antidopaminergic drugs including some benzamides, so it is prudent to refrain from prescribing this product in known or suspected carriers of pheochromocytoma

· In association with levodopa (see section Interactions with other medicinal products and other forms of interactions)

Neuroleptic malignant syndrome

As with other neuroleptics, the occurrence of neuroleptic malignant syndrome (hyperthermia, muscle stiffness, neurovegetative disorders, altered consciousness, increased CPK) is possible. In case of hyperthermia, especially with high daily doses, any antipsychotic treatment, including amisulpride, should be discontinued.

The amisulpride prolongs in a dose-dependent manner the QT interval. This effect, known to potentiate the risk of occurrence of severe ventricular arrhythmias, in particular of torsades de pointes, is increased by the presence of bradycardia, hypokalaemia, congenital long QT Or acquired (combination with an interval-increasing drug QTc) (see section Effects, undesirable)

It is therefore appropriate, when the clinical situation permits, to ensure before any administration of the absence of factors which may favor the occurrence of this disorder of the rhythm

· Bradycardia less than 55 beats per minute

· Hypokalemia

· Congenital prolongation of the QT interval

· Ongoing treatment with a medication likely to result in marked bradycardia (

Although the causes of death in clinical trials with atypical antipsychotics were varied, most of these deaths appeared to be either of cardiovascular origin (eg heart failure, sudden death) or infectious ( For example pneumonia).

Cases of venous thromboembolism (VTE) have been reported with antipsychotics.) Since patients treated with antipsychotics often have risk factors for VTE, all risk factors for VTE should be Identified before and during treatment with AMISULPRIDE ACTAVIS and preventive measures should be taken where appropriate (see section Effects, undesirable).

Cases of hyperglycemia or glucose intolerance and of the onset or exacerbation of diabetes have been reported in patients treated with certain atypical antipsychotics including amisulpride (see section 4.4) .

Patients treated with AMISULPRIDE ACTAVIS should be monitored clinically and biologically according to current recommendations. Special attention should be paid to patients with diabetes or who have diabetes risk factors

Convulsion

The amisulpride may decrease the threshold, epileptogenic. Patients with a history of seizures should therefore be closely monitored during treatment with AMISULPRIDE ACTAVIS

Populations, special

Due to the renal elimination of the product, it is recommended to reduce the dosage in renal insufficiency or other treatment may be considered (see Dosage and Mode of Administration). There is no data in patients with severe renal impairment (see section 4.2 Posology and method of administration)

Like all antipsychotics, amisulpride should be used with caution, especially in elderly patients, because of a potential risk of sedation and hypotension. >
Like any other antidopaminergic drug, amisulpride should be used with caution, in Parkinson's, because of a risk of deterioration of the disease. Friendulpride should only be used if neuroleptic treatment is essential.

Weaning syndrome

Symptoms of withdrawal have been described after abrupt discontinuation of high doses of antipsychotics. The occurrence of involuntary movements (such as akathisia, dystonia and dyskinesia) have been reported with amisulpride. Therefore, a progressive stop of the amisulpride is advised.

Other

This medication is not recommended in combination with alcohol, antiparkinsonian dopaminergic agents, antiparasitic drugs, tetrahedrons, methadone, other neuroleptics and medicines, which can lead to torsades de pointes ( See section Interaction with other medicinal products and other forms of interaction)

Related to excipients

This medicine contains lactose and is not recommended for use in patients with galactose intolerance, Lapp lactase deficiency or malabsorption syndrome, glucose or galactose (hereditary or rare diseases). Br>

+; Sedative drugs

It must be taken into account that many drugs or substances can add up to their depressant effects of the central nervous system and contribute to diminish vigilance. These include morphine derivatives (analgesics, antitussives and substitution treatments), neuroleptics, barbiturates, benzodiazepines, anxiolytics, other than benzodiazepines (eg, meprobamate), hypnotics, antidepressants, sedatives (Amitriptyline, doxepin, mianserin, mirtazapine, trimipramine), antihistamines H1, sedatives, central antihypertensives, baclofen and thalidomide
+ Drugs capable of giving torsades of points

This severe heart rhythm disorder can be caused by a number of drugs, whether antiarrhythmic or not. Hypokalemia (see hypokalaemic drugs) is a factor in promoting bradycardia (see bradycardia drugs) or prolongation of the QT interval, congenital or acquired. >

The medicinal products concerned are class Ia and III antiarrhythmics, some of them neuroleptics.

For erythromycin, spiramycin and vincamine, only the forms administered intravenously are concerned by this interaction.

The use of a drug, twisting with another medication, is contraindicated in general.

However, methadone, as well as certain subclasses, are the exception, this rule

· Antiparasitics (halofantrine, lumefantrine, pentamidine) are only advised against with other torsadogens

· Neuroleptics capable of giving torsades de pointes are also not advised and not contraindicated with other torsadogens.
Associations contraindicated

Dopaminergic can cause or aggravate psychotic disorders. In the case of neuroleptic treatment in dopaminergic patients treated with dopaminergic patients, the latter should be gradually decreased until they stop (their sudden arrest exposes them to a risk of malignant neuroleptic syndrome ").

To date, data concerning acute overdosage with amisulpride are limited. The signs and symptoms that have been reported resulted generally from an increase in the pharmacological effects of the drug, translated into the clinical plane by: somnolence, sedation, coma, hypotension and extrapyramidal symptoms. Fatal outcomes have been reported mainly during association with other antipsychotics.

· Close monitoring of vital functions.

Monitoring cardiac monitoring (risk of prolongation of Q.T. interval) which will be continued until the patient is recovered

· In the event of severe extrapyramidal symptoms, anticholinergic therapy should be administered.

· Since amisulpride is weakly dialyzable, hemodialysis has limited interest in eliminating the product.

Pregnancy

In the animal, amisulpride has not shown reproductive toxicity. A decrease in fertility due to pharmacological effects of the drug (prolactin-dependent effect) was observed. It has not been shown to have an effect: the teratogen of amisulpride.

In clinical settings, data available during pregnancy are limited. Consequently, the safety of use of amisulpride during pregnancy has not been established. The use of amisulpride during pregnancy is not recommended unless the expected benefits justify the potential risks.

If amisulpride is used, during pregnancy the adverse effects of amisulpride may be observed in newborns. As a result, newborns should be carefully monitored.

In the absence of data on passage through breast milk, breast-feeding is contraindicated.
